TSV format is used to store data in specific text format that uses tabs as separators, instead for example commas that is reserved for CSV format.
You can import any text data files to Excel, you just have to pick a proper separator during the import procedure, so Excel knows how to read and assign the data properly in the tables.
The same can be actually done with pretty much every spreadsheet editor and you can even find online parsers/converts that can help you achieve tsv to excel conversion through website.
